fix: ensure Claude Code finds skills in ~/.claude/commands/

1. Skills API: accept optional cwd query param so project-level skills
   are scanned from the session's working directory, not the standalone
   server's process.cwd().
2. SDK env: explicitly set HOME so Claude Code can resolve ~/.claude/
   for global skills discovery in packaged builds.
